PS Of the 22 fast-food businesses in a small city, the numbers that have a drive-up window, outside seating, or delivery Page 58 service are summarized as follows: 7 have delivery service: IS have outside seating: 13 have a driveup window, 9 have a drive- up window and outside seating; 3 have outside seating and delivery service: 3 have delivery service and a drive-up window; and 2 have all three services. How many of these businesses have only a drive-up window?
There are 4 fast-food businesses in this small city that have only a drive-up window.
To determine the number of fast-food businesses that have only a drive-up window, we need to subtract the businesses that have a drive-up window and other services from the total number of businesses with a drive-up window.
According to the given information:
Total number of fast-food businesses = 22
Number of businesses with delivery service (D) = 7
Number of businesses with outside seating (O) = 13
Number of businesses with a drive-up window (W) = 13
Number of businesses with both a drive-up window and outside seating (W ∩ O) = 9
Number of businesses with both outside seating and delivery service (O ∩ D) = 3
Number of businesses with both delivery service and a drive-up window (D ∩ W) = 3
Number of businesses with all three services (D ∩ O ∩ W) = 2
To find the number of businesses with only a drive-up window:
Number of businesses with only a drive-up window = Number of businesses with a drive-up window (W) - Number of businesses with both outside seating and a drive-up window (W ∩ O)
Number of businesses with only a drive-up window = 13 - 9 = 4
Therefore, there are 4 fast-food businesses in this small city that have only a drive-up window.

A government starts off with a total debt of $5.5 billion. In year one, the government runs a deficit of $600 million. In year two, the government runs a deficit of $1.5 billion. In year three, the government runs a surplus of $400 million. What is the total debt of the government at the end of year three?
Assuming the government runs a deficit of $200 million in year three, what is the total debt of the government at the end of year three?
If a government runs a budget deficit of $5 billion dollars each year for ten years, then a surplus of $2 billion for five years, and then a balanced budget for another ten years, what is the government debt?
The total debt of the government at the end of year three is $7.2 billion.
How does the government's deficit and surplus impact the total debt by the end of year three?Starting with a total debt of $5.5 billion, the government's deficits of $600 million in year one and $1.5 billion in year two contribute to an increase in the debt. However, in year three, the government runs a surplus of $400 million, which helps reduce the debt.
Thus, the total debt at the end of year three is calculated by adding the initial debt and deficits, and subtracting the surplus. In this case, the total debt at the end of year three is $7.2 billion.
How does assuming a deficit of $200 million in year three affect the government's total debt at the end year three?Assuming the government runs a deficit of $200 million in year three, the calculation changes. With the initial debt of $5.5 billion, the deficits of $600 million in year one and $1.5 billion in year two, and the additional deficit of $200 million in year three, the total debt at the end of year three would be $7.8 billion. This demonstrates how the deficit amounts impact the overall debt accumulation.
If a government runs a budget deficit of $5 billion each year for ten years, resulting in a total deficit of $50 billion, followed by a surplus of $2 billion per year for five years, reducing the debt by $10 billion, and then maintaining a balanced budget for another ten years, the government debt would amount to $40 billion. The deficits over the initial ten years lead to a significant accumulation of debt, but the subsequent surpluses help mitigate the debt by reducing the deficit. Finally, the balanced budget in the later years ensures that there is no further increase in debt. Understanding the interplay between deficits, surpluses, and a balanced budget is crucial to grasp the long-term implications on government debt and fiscal stability.

To determine the percentage of Sara's students who answered at least half of the quiz questions incorrectly, we need more information than the relative cumulative frequency of students who earned a score of 21 or higher.
The cumulative frequency only tells us the percentage of students who scored 21 or higher, but not the percentage who answered at least half of the questions incorrectly.To calculate the percentage of students who answered at least half of the quiz questions incorrectly, we would need additional data such as the scores or the number of questions on the quiz.

Nogan Airport has three runways. The airport dedicates two runways to serve departing flights and one
runway to serve arriving flights. If used for departure, a runway can serve 10 flights per hour; if used for
arrival, a runway can serve 15 flights per hour. The time it takes for a plane to use a runway (either to
depart or to land) is exponentially distributed.
The flight schedule in the morning is as follows. The time between two consecutive departing flights is
exactly 5 minutes. The time between two consecutive arriving requests is exponentially distributed,
with an average of 10 minutes. When an arriving flight approaches the airport, it radios the control
tower and requests permission to land. The air traffic controller responds instantly by assigning the
plane a position in queue on a first-come-first-serve basis.
(a) On average, how much time elapses between a plane’s radioing of the control tower and its eventual
completion of the entire arriving process in the morning? (1 point)
On average, it takes approximately 14 minutes for a plane to complete the entire arriving process, from radioing the control tower to landing on the runway, in the morning at Nogan Airport.
To determine the average time that elapses between a plane radioing the control tower and its completion of the entire arriving process in the morning, we need to consider the different steps involved in the process.
Radioing the control tower: The time between two consecutive arriving requests follows an exponential distribution with an average of 10 minutes. Hence, on average, it takes 10 minutes for a plane to radio the control tower after the previous plane.
Assigning position in queue: The air traffic controller assigns the plane a position in the queue on a first-come-first-serve basis, implying that there is no additional delay for this step.
Landing on the runway: Once the plane reaches the front of the queue, it lands on the runway. The time it takes for a plane to use a runway, either for landing or departing, follows an exponentially distributed process.
Since the runway dedicated to arrival can serve 15 flights per hour, the average time it takes for a plane to complete the landing process is 1/15 hour, or 4 minutes.
Considering these steps, the average time that elapses between a plane radioing the control tower and completing the entire arriving process in the morning can be calculated as follows:
Average time = Time to radio the control tower + Time to land on the runway
= 10 minutes + 4 minutes
= 14 minutes

Find the area under the normal curve up to z=0.36; that is, find P(Z≤0.36) give your answer as a probabilay rounded to two decimal places, so in the format 0.XX.
The area under the normal curve up to z = 0.36 is P(Z ≤ 0.36) and is equal to 0.64. To find the value of P(Z ≤ 0.36), the standard normal distribution table is used. We can find the value by looking up the closest z-value on the standard normal distribution table.
The value of 0.36 is not exactly found in the table, however, the closest value to it is 0.35. Using the standard normal distribution table, the area to the left of z = 0.35 is 0.6368. Since we need to find P(Z ≤ 0.36), this area needs to be added to the area from 0.36 to 0.35, which is 0.0032. Adding the two values will give us the answer: 0.6368 + 0.0032 = 0.64.Therefore, the area under the normal curve up to z = 0.36 is P(Z ≤ 0.36) and is equal to 0.64. In order to find the area under the normal curve up to z = 0.36, we need to find the value of P(Z ≤ 0.36), which is the probability of a standard normal variable taking a value less than or equal to 0.36. To find this probability, we use the standard normal distribution table, which provides the area to the left of a given z-value.The standard normal distribution table is usually presented in the form of a table that gives the area to the left of a given z-value. For example, if we want to find the area to the left of z = 1.96, we look up the value 1.9 in the first column and the value 0.06 in the second column. We then add these two values to get the area to the left of z = 1.96, which is 0.9750. Similarly, we can find the area to the left of any other z-value by using the standard normal distribution table.To find the area under the normal curve up to z = 0.36, we first need to find the closest value to 0.36 in the standard normal distribution table. In this case, the closest value is 0.35. We then look up the area to the left of z = 0.35 in the standard normal distribution table, which is 0.6368. Since we need to find the area to the left of z = 0.36, we need to add the area from 0.35 to 0.36, which is 0.0032. Adding these two values gives us the area under the normal curve up to z = 0.36, which is 0.6368 + 0.0032 = 0.64.
The area under the normal curve up to z = 0.36 is P(Z ≤ 0.36) and is equal to 0.64. This means that the probability of a standard normal variable taking a value less than or equal to 0.36 is 0.64. To find this probability, we used the standard normal distribution table, which provides the area to the left of a given z-value. We found the area to the left of z = 0.35, which is the closest value to 0.36 in the standard normal distribution table. We then added the area from 0.35 to 0.36 to get the area under the normal curve up to z = 0.36, which is 0.64.

Find the side labeled x. State your answer rounded to 5 decimal places. x = Evaluate the expression without using a calculator. sin Pi/6 + cos Pi/6
The final answer rounded to 5 decimal places is:`x = 0.57735`
A) Given trigonometric expression is;`sin (π/6) + cos (π/6)`
Using the trigonometric values of π/6 from the trigonometric table, we have:
sin π/6 = 1/2cos π/6 = √3/2.Substituting the trigonometric values into the given expression, we have:
sin π/6 + cos π/6= 1/2 + √3/2= (1 + √3)/2
Therefore, the value of `sin (π/6) + cos (π/6)` is `(1 + √3)/2`.
B) Now, coming to the next part, we need to find the side labeled x.
The value of the tangent of an angle is equal to the ratio of the opposite side and the adjacent side. Thus, we can write:tan θ = Opposite side/Adjacent side
We have the values of the angle and the adjacent side, using that, we can find the opposite side as follows:`
tan 30° = Opposite side/1`Opposite side = `tan 30°`Opposite side = `(1/√3)`
Therefore, the side labeled x is `(1/√3)`.
